The map of China is long from north to south.

The National Map Publishing House published the new edition of "The Whole Map of the Chinese People * * * and the Country" in 213, which showed the complete territory of China in vertical form, and for the first time showed the South China Sea islands and the mainland in the same scale on the map, showing the land and sea territory of China more truly and intuitively.

Corrected the disadvantages of small land and light sea in horizontal map. Lu Rude, a special professor of Dalian Naval Academy, interprets the changes and significance of vertical maps.

The orientation and orientation of China map are generally consistent with other maps, that is, due north orientation (due north faces the top of the drawing). Occasionally, under some circumstances, such as being influenced by some map projection deformation or making maps with bird's-eye views in different directions, the true north direction of such China maps may not be above the map.

Extended information:

The vertical map of the People's Republic of China is the first large-format vertical map in China. The South China Sea and islands are on the same scale as the mainland, and the South China Sea islands are no longer represented as illustrations. Geographical information such as islands and reefs of the South China Sea Islands is marked in detail, including dongsha islands, Xisha Islands, zhongsha islands and Nansha Islands of the South China Sea Islands in China. The geographical relationship and administrative divisions of Hainan Province, Hainan Island and South China Sea Islands have become clearer and clearer in the map.

The vertical version of the Map of World Knowledge is a breakthrough from the traditional horizontal version of the Map of the World, which means that the horizontal version of the map, which has been used for more than 4 years, is no longer "unified". It overcomes the defects of great deformation of Antarctica and Arctic Ocean on the traditional world map, and at the same time, it is more intuitive to explain the north-south direction, and the blue sea area is more clear.

The terrain in the map is calculated and generated by fully digital elevation data, and there is no artificial description component. With the method of layered color, the relief of the world's oceans is truly expressed.
